Upload a new background/banner photo.

This tool modifies account metadata by uploading and setting a new profile asset. While reversible (a user can replace it again), it changes the state of the user's LinkedIn profile. The blast radius is limited to profile aesthetics and account control; misuse could deface a profile or change its presentation, but cannot delete data irreversibly or execute arbitrary operations.
From the tool's definition Tool description states 'Upload a new background/banner photo' — this creates or modifies user profile data (the background/banner image) reversibly.

PolicyLayer is an MCP gateway — it sits between your AI agents and LinkedIn Intelligence MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for upload_background_photo:
{
"version": "1",
"default": "deny",
"tools": {
"upload_background_photo": {
"limits": [
{
"counter": "upload_background_photo_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
